Anthony Lewis's free-speech credentials are impeccable: among other things, the former New York Times columnist is James Madison Visiting Professor of First Amendment Issues at Columbia University's journalism school; was fêted by the National Coalition Against Censorship this past fall; and chronicles the First Amendment's history in his most recent book, Freedom for the Thought That We Hate: A Biography of the First Amendment (Basic Books).

Recently, though, Lewis has been reassessing the legal standard for how far threatening speech should be allowed to go. The key precedent here is 1969's Brandenburg v. Ohio, in which the Supreme Court ruled that calls for violence against Jews and blacks at a Ku Klux Klan rally were legal: such advocacy is protected, the court found, unless it's "directed to inciting or producing imminent lawless action and is likely to incite or produce such action."

Harvey Silverglate — the chairman of the board of directors of the Foundation for Individual Rights in Education, and a regular Phoenix contributor — explains the "imminence standard" thusly: "If you get a speaker who gets up there and says, 'All Jews and blacks should be hung,' that is fully protected. But if the speaker says, 'There's a Jewish neighborhood or a black neighborhood two blocks down the road. Let's go down there and lynch them,' that gets into an area where the speech that's recommending action becomes more realistic — more imminent."

In Freedom for the Thought That We Hate, however, Lewis suggests that, in the context of the so-called War on Terror, a more expansive reading of Brandenburg's imminence standard might be appropriate. And he makes a similar — albeit hypothetical — argument regarding anti-Obama speech.

"If somebody tried to assassinate Obama," says Lewis, "and upon further examination it turned out that they were a regular listener to Sean Hannity [of Premier Radio, ABC Radio, and Fox News] — and decided, on the basis of Hannity's many broadcasts, that Obama was trying to destroy the United States — would that justify shutting Hannity down and curbing speech in some way? It's hard to say . . . but if it had that effect, surely the imminence requirement is at least partially met."

Surprisingly, Lewis isn't the only civil libertarian thinking along these lines. Gene Policinski, the vice-president and executive director of the Tennessee-based First Amendment Center, says there's a chance that the courts will pay closer attention to extreme anti-Obama speech than they have to speech regarding previous presidents. "I think there's great concern, since he's the first African-American president," says Policinski. "And given our history of violence directed at African-Americans — particularly those who stand out by challenging the status quo — the courts may see these kinds of expression in a much more serious and immediate way." (One of those African-Americans, Martin Luther King, was assassinated in the state where the First Amendment Center is headquartered.)

Fighting back Thanks to a federal law that codifies discrimination against same-sex couples, more than 15,000 legally married couples (and an untold number of children) are being denied basic benefits, such as the right to file their taxes jointly, or Social Security payments and health-insurance subsidies.

Free speech for me, but not for thee Last Thursday's Supreme Court opinion striking down corporate campaign advertising restrictions might as well have been divorce papers in the rocky marriage between the political left and the First Amendment.

Impeach John Roberts It is time for an enterprising and courageous member of the US House of Representatives to file articles of impeachment against the chief justice of the United States Supreme Court, John Roberts. The charge: lying under oath.

Policy matters Identifying and living as a transgender person has intense emotional implications that we touch on in this week's story. But here, as with most social issues, the personal is also political.

Marriage activists get closure, look forward Congresswoman Chellie Pingree expressed what many in the room were feeling at Equality Maine’s annual dinner celebration on Saturday night: the function room at the Holiday Inn by the Bay on Spring Street elicits “a little bit of PTSD” for Maine’s gay-rights supporters.

BULLY FOR BU! | March 12, 2010 After six years at the Phoenix , I recently got my first pre-emptive libel threat. It came, most unexpectedly, from an investigative reporter. And beyond the fact that this struck me as a blatant attempt at intimidation, it demonstrated how tricky journalism's new, collaboration-driven future could be.

STOP THE QUINN-SANITY! | March 03, 2010 The year is still young, but when the time comes to look back at 2010's media lowlights, the embarrassing demise of Sally Quinn's Washington Post column, "The Party," will almost certainly rank near the top of the list.

RIGHT CLICK | February 19, 2010 Back in February 2007, a few months after a political neophyte named Deval Patrick cruised to victory in the Massachusetts governor's race with help from a political blog named Blue Mass Group (BMG) — which whipped up pro-Patrick sentiment while aggressively rebutting the governor-to-be's critics — I sized up a recent conservative entry in the local blogosphere.

RANSOM NOTES | February 12, 2010 While reporting from Afghanistan two years ago, David Rohde became, for the second time in his career, an unwilling participant rather than an observer. On October 29, 1995, Rohde had been arrested by Bosnian Serbs. And then in November 2008, Rohde and two Afghan colleagues were en route to an interview with a Taliban commander when they were kidnapped.

POOR RECEPTION | February 08, 2010 The right loves to rant against the "liberal-media elite," but there's one key media sector where the conservative id reigns supreme: talk radio.
